Seasonal species composition and distribution of barnacle larvae in Avacha Inlet (Kamchatka)

The annual dynamics of the numbers and distribution of barnacle larvae in Avacha Inlet were studied. Planktonic cirripede larvae were found in the area studied from late March at a temperature of −1–0°C until October. The highest density of 18 000 m−3 was observed in mid-April.

Description
Summary:The annual dynamics of the numbers and distribution of barnacle larvae in Avacha Inlet were studied. Planktonic cirripede larvae were found in the area studied from late March at a temperature of −1–0°C until October. The highest density of 18 000 m−3 was observed in mid-April. Balanus crenatus and Semibalanus cariosus were the dominant species, Chthamalus dalli and Balanus balanus larvae being less abundant. Naupliar density was maximal at 0–5 m and decreased with depth. Maximum densities of B.crenatus larvae were observed in Rakovaya Bay, where there are many ships and a seawater-cooled power station. Most nauplii of the intertidal barnacle S.cariosus , which prefers wave-exposed open coast, were taken in the Avacha Inlet narrows Settling on artificial substrata was most intensive from late May to early June
